MCP79522T-I/MN

Real Time Clock Overview

The MCP79522T-I/MN is a Real-Time Clock (RTC) integrated circuit manufactured by Microchip Technology. It features an SPI interface and includes 2Kb EEPROM and 64B SRAM. The device supports EUI-64 identification. It operates within a supply voltage range of 1.8V to 3.6V and functions at temperatures from -40°C to +85°C. The component is housed in a 10-pin TDFN package measuring 3x3x0.8mm.

Real Time Clock Feature Summary

• Integrated 2Kb EEPROM for non-volatile data storage
• Includes 64B SRAM for user-defined memory tasks
• Supports EUI-64 unique identifier for device tracking
• SPI serial interface for communication

Real Time Clock Applications

• General purpose real-time clocking systems
• Data logging applications requiring timestamping
• Embedded devices needing persistent timekeeping with backup power

Real Time Clock Procurement Notes

Verify the specific suffix 'MN' corresponds to the TDFN-10 package configuration as indicated in distributor listings. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure design compatibility with the 1.8V to 3.6V operating voltage range.

Real Time Clock Selection Notes

Select this model when 2Kb EEPROM capacity is required, distinguishing it from the MCP79510 which offers only 1Kb. The TDFN-10 package suits space-constrained PCB layouts. Verify that the host system supports SPI communication protocols compatible with the MCP795xx family specifications.

Real Time Clock Part Context

This part belongs to the MCP795xx family of compact RTCs. It shares functional similarities with the MCP79520 and MCP79522 variants but differs in package type and specific memory configurations. The 'I' designation indicates industrial temperature range operation.

Real Time Clock Replacement Considerations

The MCP79520T-I/MN is a related variant within the same family. Verify if the reduced 1Kb EEPROM capacity of the MCP79520 meets application requirements before substitution.
